ADJUSTABLE CREASING OR SCORING MECHANISM.

Application filed April 10, 1914-.

To all whom it may concern Be it known that I, ELMER E. WECK, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Adjustable Creasing or Scoring Mechanism, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Where books or pamphlets are covered with one-piece flexible paper covers it is desirable that each cover be creased or scored along separated parallel lines spaced apart a distance just equal to the thickness of the book or pamphlet; and, in order to lessen the danger of loosening the cover when the book or pamphlet is being used, it is desirable to provide additional scoredor creased lines which run along the cover on the front and back parallel with and a short distance from the back edge.

Books and pamphlets provided with paper covers of course vary greatly in thickness and therefore a corresponding variation in the adjustment of the scoring or creasing devices must be made in a machine used in a printing establishment or bindery for creasing the covers as heretofore explained. As far as I am aware, these adjustments have heretofore been made wholly by employing numerous interchangeable parts from which the proper selection has been made to produce, when assembled, a creasing or scoring device containing the proper spacing. This expedient of course involves a considerable initial expense and trouble and delay in adjusting the machine when changing from one piece of work to another.

The object of my invention is to produce a simple and novel self-contained mechanism which shall be capable of scoring a paper cover or the like along parallel lines spaced apart any desired distance, and which may be adjusted quickly and conveniently and changed from one kind of work to another.

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my invention and of its object and ad- Specifieation of Letters Patent.

Patented Sept. 5, 1916. Serial No. 830,876.

vantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure 1 is a side view of a mechanism arranged in accordance with a preferred form of my invention, no part of the mach1ne for containing this mechanism, except portions of the supporting shafts for the mechanism, being shown; Fig. 2 is a view similar to Fig. 1, showing the parts adjusted so as to give a different spacing from that which will be obtained from the adjustment shown in Fig. 1; and Fig. 3 is a section taken on a plane containing the axes of the two coijperating parts of the mechanism.

Referring to the drawing, 1 and 2 represent two parallel shafts which may be the shafts of an ordinary perforating and scoring machine on which the perforating cutters or scoring devices are mounted. On the shaft 1 is a sleeve 3 having between the ends thereof a projecting annular flange, l, provided at the periphery with a cylindrical shoe or anvil, 5, concentric with the axis of the shaft. Arranged on the sleeve at opposite sides of the flange 4 are suitable holders, 6 and 7, arranged to slide lengthwise of the sleeve from and toward the shoe or anvil. In the holder 6 is mounted a scoring or creasing disk, 8, and in the holder 7 is mounted a similar scoring or creasing disk, 9; the two disks being co-axial with the shaft 1 and projecting slightly beyond the surface of the shoe or anvil. In the ar rangement shown, each of the holders 6 and 7 is provided on the side next to the flange 4 with a screw threaded hub, 10. The members 8 and 9 are in the form of washers having central openings just large enough to fit about the hubs, and nuts 11 being arranged on the hubs to clamp the washers against the holders. Furthermore, the sleeve 3 is provided with two elongated slots 12, near opposite ends and each ofthe holders 6 and 7 isprovided with a set screw, 13, passing through the same and through one of the slots. The arrangement is such that the set screws prevent the holders from turning on the sleeve and, when screwed tightly against the shaft 1 prevent relative rotary motion between the sleeve of the holders and the shaft. When the set screws are loosened slightly, so as to bring them out of engagement with the. shaft 1, the holders maybe adjusted along the sleeve and the sleeve itself, if desired, may be ad justed along the shaft.

On the shaft 2 is a sleeve, 14, having between its ends a projecting annular flange,

.15, and having that portion between the flange and one of the ends reduced in di ameter as indicated at'16. Surrounding the larger portion of the sleeve 14 is a creasing or perforating disk, 17, in the form of a Washer having a central opening large enough to receive the sleeve. The member 17 lies against the flange 15. Beside the creasing or scoring member 17 is a cylindrical shoe or anvil, 18, which, together with the member 17 may be clamped upon the sleeve by means of a nut, 19, screwed upon the end of the sleeve and forcing the two members 17 and 18 toward the flange 15. On the reduced end, 16, of the sleeve 14 is another sleeve, 20 having at its inner end a flange, 21, corresponding to the flange 15. On the sleeve 20 are arranged a scoring or creasing member, 22, and an anvil or shoe, 23, similar to the members 17 and 18, re spectively; the members 22 and 23 being clamped between the flange 21 and a nut, 24, on the outer end of the sleeve 20. In the specific arrangement shown, there is a set screw, 25, which passes down through the members 18 and 14 to hold the device upon the shaft 2 while there is another set screw 26 which passes down through the members 20 and 23-and through an elongated slot 27 in the member 16, thus permitting a relative axial movement between the members 17 and 22 without requiring both of these members tobe moved relative to the supporting shaft. It will of course be understood, however, that it is not essential that one of the scoring or creasing members be fixed to the shaft. The set screw26 in the slot 27 permits the scoring or creasing device 22 and its holder to be adjusted axially within limits and be locked in any desired position in the same manner as heretofore explained with respect to the set screws 13 in the slots 12.

The parts are so arranged that the scoring or creasing devices 8 and 9 engage or nearly engage with the anvils or shoes, 18 and 23 respectively while the scoring or creasing devices 17 and 22 engage or nearly engage with the'shoe or anvil, 5. .The flanges 15 and 21 are made thin enough so as to permit the members 17 and 22 to be brought together so as to be separated from each other a distance equal to the thickness of the thinnest book or pamphlet for which it may be desired to score or crease a cover.

In the same way, the shoe or anvil 5 is made wide enough to permit the members 17 and 22 to be moved apart a distance equal to the thickest book or pamphlet whose cover is to be scored, without passing beyond the ends of the shoe or anvil.

In Figs. 1 and 3 the parts are illustrated as adjusted for working on the cover of the thinnest book, the paper being adapted to pass through the mechanism and to be scoredalong four lines. InFig. 2 the parts are shown at the other extreme of adjustment. It will of course be understood that any other desired adjustment between these two extremes may be obtained.

It will thus be seen that any desired adjustment may be obtained by the mere act of loosening the three set screws and shifting the parts of the mechanism so as properly to space the several scoring or creasing devices,the set screws being then set so as to lock the parts of the mechanism in the adjusted positions.

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described, but intend to cover all forms and arrangements which come within. the terms employed in the definitions of my invention constituting the appended claims.
